Light Emitting Diode (LED) Structure Having Single Epitaxial Structure Separated Into Light Emitting Zones

A light emitting diode (LED) structure comprising:

• an epitaxial structure separated into a plurality of electrically separate light emitting zones, the epitaxial structure comprising an n-type layer, a p-type layer, and an active layer configured to emit an emitting light having a particular wavelength, each light emitting zone comprising a portion of the epitaxial structure geometrically configured with an effective emission area;
• a wavelength conversion member on the effective emission area of each light emitting zone configured to convert an emitting wavelength of the emitting light to a desired color;
• and
• a metal layer on the epitaxial structure configured as a common electrode in electrical communication with the light emitting zones;
• wherein the effective emission area for each light emitting zone is different.
